The elaboration of Biol II-G was proposed to improve its properties and value of a cow biol I-G from a 10 m3 tubular biodigester which registered pH values on average 7.05 und, electrical conductivity 5.01 dS / m. To produce it, lactic fermentation was carried out for five days. The properties of the obtained product were evaluated such as the level of pH and lactic acidity, the physico-chemical characteristics: macronutrients (N, P, K) and micronutrients (Ca, Mg, Na, Fe, Cu , Zn, Mn and B) and heavy metals (Cd, Cr and Pb), microbiological (Fecal coliforms, Total coliforms, E. coli., Salmonella sp.); and the optimal dilution of application in a bioassay. Previously, nine mixtures to be fermented were tested and an optimal one was selected: cow biol (75 percent), microbial consortium (15 percent) and cane molasses (10 percent). A pilot scale was worked with this treatment and a final pH of 3.89 was reached at room temperature and a lactic acid content close to 1.92 percent lactic acidity (A.L.) on the fifth day. Potassium (macronutrient) increased by 58 percent while magnesium (micronutrient) increased by 230 percent with respect to the biol of I-G. The acidification of the fermentation process ensured the elimination of pathogens and through a phytotoxicity test it was determined that the fertilizer diluted to 0.1 percent favored the growth of lettuce seedlings. The liquid fertilizer produced presented characteristics typical of lactic fermentation and in accordance with similar experiences: generation of lactic acid, supply of nutrients, microbiological safety and without phytotoxic effects. It is highlighted that the material costs were low and the emission of greenhouse gases and other environmental problems was avoided by valuing the waste.
